HOLLINS STORAGE RACK March 8, 1966 2 Sheets-Sheet 2 Filed Aug. 10, 1964 INVENTOR EW/5 6T /v/L//VS BY La, MM /Qf ATTORNEY United States Patent O 3,239,069 STQRAGE RACK Lewis S. Hollins, 1 Chester Drive, Great Neck, N.Y. Filed Aug. 10, 1964, Ser. No. 388,424 13 Claims. (Cl. 211-60) This invention relates to a storage rack. In the main such a rack is intended to be used as a holder for cosmetic accessories and hence will be referred to hereinafter mainly as a cosmetic rack. My invention, however, resides in the structural features of the rack which later will be described and claimed and is not to be limited to the storage of any particular articles thereby.

With the burgeoning vogue for female beautification and with the sophisticated and everchanging styles that come and go, cosmetic articles have so proliferated that a typical fernales assortment thereof overflows conventional storage places, such for example, as -Vanity and dresser tops and bathroom cabinets. Due to the accumulation of lipsticks, rouges, eye makeup, pencils and brushes for cosmetic application, bobby-pins, Q-tips, nail files and various and sundry articles of a similar nature, a serious problem has developed as to neat and accessible storage. Their oblong, round and irregular shapes, their tubular containers with unique trim and their disproportionate diameters makes it difficult to arrange the articles in any compact and orderly pattern or grouping with the result that even the most meticulous woman has difliculty in avoiding their random disarray and the need for an abundance of shelf or other horizontal storage space. Bathroom cabinets overflow with the articles, and drawers, shoeboxes and dresser and vanity tops are veritable jungles of confusion. The articles cannot be stacked upon one another because of their irregular shapes and elongated proportions. They cannot be rested lengthwise on a llat surface because they tend to roll away. Because of their irregular sizes and shapes they must, in elfect, be laid flat in a single layer if access to them is to be convenient, or they must be stored almost helter-skelter in a deep container if they are not to take up too much space, and in this latter event a woman must rummage through such a container to find the particular item which she wants to use at any given time.

It is an object of my invention to provide a storage rack which will avoid all of the foregoing ditliculties.

More particularly, it is an object of my invention to provide a rack of the character described which will enable irregularly shaped but generally elongated articles to be held in a more or less regular array Where access thereto is rapid and easy and yet where they consume a minimum of horizontal space, as for example, in a medicine chest or a vanity or dresser top.

It is another object of my invention to provide a rack of the character described which will hold such articles close to one another in a side-by-side orderly relationship which is neat to the eye and yet compact enough to minimize the amount of room required.

It is another object of my invention to provide a rack of the character described having all of the foregoing advantages and which further is so constructed as to enable plural racks to be vertically stacked upon one another, so that a maximum of head room can be utilized, this being in contrast to prior random arrangements wherein such articles had to be spread out in a single layer if access thereto and selection thereof was to be quick and easy.

It is another object of my invention to provide a rack of the character described which can be placed in several different positions on a horizontal surface so that, depending to a large extent upon the desires of the user or the space available, the articles to be stored can be held in many different ways.

Patented Mar. 8, 1966 It is another object of my invention to provide a rack of the character described in which elongated articles and round articles, both of which are notoriously unstable when set either on their ends or on their sides, are held in a fixed stable equilibrium.

It is another object of my invention to provide a rack of the character described in which the articles stored can -be so disposed that they will not tend to be accidentally displaced even when the rack or the articles are inadvertently struck.

It is another object of my invention to provide a rack of the character described which has an attractive trim appearance, occupies a minimum of space, is inexpensive to make, is rugged and trouble-free in use, has no moving parts, and requires no instructions for proper handling.

Other objects of my invention in part will Ibe obvious and in part will be pointed out hereinafter.

My invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplilied in the storage rack hereinafter described and of which the scope of application will be indicated in the appended claims.

In the accompanying drawings in which is shown one of the 'various possible embodiments of my invention,

FIG. l is a perspective view of a storage rack constructed in accordance with my invention and shown so positioned that its characterizing rank of tubular repositories are inclined with their longitudinal axes sloping rearwardly and downwardly at a gentle 4angle to the horizontal and with their unconstricted open ends at the front of the rack;

FIG. 4 is a view similar to FIG. l, but illustrating the rack turned about its elongated horizontal axis so that the face 'shown at the front in FIG. 1, is now at the top of the rack whereby the rank of tubular repositories face in a generally upward direction rather than in the generally forward direction illustrated in FIG. 1;

FIG. 5 is an end view of a vertical stack of racks, only two such racks being illustrated to conserve space in the drawings; and

FIG. `6 is an enlarged sectional view taken substantially along the line 66 of FIG. 5.

Referring now in detail to the drawings, the reference numeral' 10 denotes a storage rack embodying my invention and designed primarily for storing cosmetic articles. By way of example, typical -cosmetic articles which the rack is intended to accommodate include lipsticks of all varieties of shapes and sizes, including short lipsticks, long lipstricks and thin (pencil-like) lipsticks, liquid and solid rouges, mascara pencils, mascara rod applicators, mascara brush applicators, cosmetic applicators and brushes of all types, eyebrow pencils, bobby pins, hairpins, Qtips, eye shadow, ointment tubes, etc. Although I have mentioned many examples of cosmetic articles, it is to be understood that it also is within the scope of my invention to utilize the rack 10, soon to be described in detail, as a storage receptacle for sundry other types of articles. Exempliicative thereof are screw drivers, chisels, nails, screws, cotter pins, bolts, drill bits, crayons and pencils. Y

The storage rack 10 is constituted by a pair of end walls 12 supporting between them an elongated frame 14. Pursuant to a feature of my invention the entire rack, including the end walls and frame, is formed in one piece; that is to say, each and every component of the rack is unitary with every other component. They are not individual components which must be assembled with one another through the use of a fastening means. Rather, the sundry components are, as just stated, all of a piece. To this end, in the preferred form of my invention the rack is molded, that is to say, cast, through the use of a mold into which a solidiiiable material is introduced in fluid form. In one acceptable form of the rack the molding material is a synthetic resin, either thermoplastic or thermosetting. I have found excellent results are obtained with a thermoplastic synthetic resin and for this purpose may use any one of the well-known and widely accepted resins of the foregoing nature, examples being cellulose acetate, cellulose acetate butyrate, acrylic resins, polyamide resins, styrene and a butadiene modified styrene. Other suitable moldable materials are zinc and aluminum die-casting alloys, and glass, it being understood that glass may be fabricated to the shape about to be described in any conventional glass-forming machine. Another suitable material is clay which can be shaped into the configuration hereinafter described and thereafter baked so that the rack in such case will either be pottery or china. Still further, the rack may be carved from a solid block of material, as for example from wood.

The two end walls 12 have their exterior broad faces fiat, that is to say, plane, and said end walls are parallel to one another and perpendicular to the longitudinal axis of the elongated frame 14 which extends between them. In this manner the user can, if she desires, stand the storage rack on end, which is to say, with either end wall flat upon a at horizontal supporting surface. The rack thereby will be in erect position. Although this does not constitute the preferred method of utilization, -under certain conditions it may be desirable.

Each of the end walls 12 includes at least one straight peripheral edge 16, this being the peripheral edge that will rest upon a flat horizontal supporting surface when the bottom of the rack is lowermost. Hence, for purposes of ready identification, the straight edge 16 will be hereinafter referred to as the bottom ed-ge of an end wall. The bottom edges 16 of the two end walls are transversely aligned and are, therefore, parallel to one another.

Preferably, moreover, at least one additional peripheral edge 18 of each end wall is straight, and, furthermore, such edge 18 is perpendicular to the straight bottom edge 18. Inasmuch as the edge 18 will be at the back of the rack when the rack is in its most preferred position, said edge will hereinafter be called the back edge.

For purposes of appearance, the front peripheral edge 20 and top peripheral edge 22 of each end wall likewise is straight and is either perpendicular or parallel, as the case may be, to the bottom and back edges 16, 18, so that, in all, the four straight peripheral edges which deiine each end wall are arranged in the shape of a square. Both end walls are similarly dimensional, so that their square peripheries are transversely aligned.

For a reason which later will be mentioned, the bottom back corner of each end wall is formed with a notch 24. The notches in the two end walls are transversely aligned.

The front face 26 of the frame, which is to say, the face of the frame which is at the -front of the rack when the bottom edges 16 are lowerrnost, is formed in three transversely elongated segments. These are: a central segment 28, a lower segment 30 (see FIG. 2) and an upper segment 32.

The central segment 26 is narrow in comparison with the height of the rack, for example, constituting approximately one-quarter of the height. This central segment is substantially ilush with the front edges 20 and the lower edge of the central segment is a short distance above the bottom edges 16. The lower segment slopes rearwardly and downwardly from the lower edge of the central segment, the angle of inclination of the lower segment being approximately 60 to the plane of the front face of the central segment. Both the central segment and the lower segment are fiat.

The central, lower and upper segments, as well as the end walls, are of slight thickness, which is to say they are in the form of flat sheets that are thick enough to be self-supporting, strong and stiff. This minimizes the amount of material necessary and thereby makes the rack economical to manufacture when it is fashioned from a hot fluid material which is solid at room temperatures.

The upper segment 32 slopes upwardly and rearwardly from the upper edge of the central segment. Said upper segment is at a gentle angle to the plane of the front face of the central segment, for example, about 30, so that with the central vsegment vertically disposed, the upper segment slopes gently upwardly and rearwardly.

In accordance with a principal feature of my invention, the upper segment 32 lis formed with a horizontal rank of rather large openings 34 which constitute the unobstructed wide mouths of tubular repositories 36 that are arranged similarly transversely aligned in a horizontal rank. The tubular repositories are of substantially right cylindrical form, there being only a slight rearwardly tapering draft in the order of about 2 to facilitate their removal from a mold. The `rear ends of the repositories are closed by bottom walls 38. As will be readily apparent from FIGS. 2 and 3, the tubular repositories likewise are thin-walled shells being only thick enough to be self-supporting, strong and stiff. The longitudinal axes of the tubular repositories are substantially perpendicular to the plane of the upper segment 32, so that with the central segment 28 vertically disposed and with the front face 26 at the front of the rack, which is a preferred position for the rack, the tubular repositories slope gently rearwardly and downwardly at an angle of about 30 which is suiiicient to prevent articles stored therein, such, for instance, as lipsticks, from jumping out of the repositories if the rack should be inadvertently struck.

The repositories are sufficiently wide to accommodate most conventional lipsticks, a suitable diameter for the repositories being in the order of seven-eighths of an inch. The depth, that is to say, length, of each repository is in excess of one-half the length of standard lipsticks, a typical depth for a repository being in the order of one and iive-eighths inches. Thereby, when a lipstick is inserted into a repository it will gravitate toward the bottom and in this position it will be in stable equilibrium, not tending to tip out of the rack.

A suitable number of tubular repositories is provided in the rack; for example, six such repositories have been found to be satisfactory, this providing an over-all end-toend length of about seven inches for the rack.

It will be appreciated that when the rack is set with the bottom edges 16 lowermost and the front face 26 foremost and substantially vertical, the tubular repositories slope gently rearwardly and downwardly. However, if desired, the rack may be used in another position, for example, with the back edges 18 lowermost. This position is illustrated in FIG. 4 and in such position the front face 26 is uppermost so that the tubular repositories now are predominantly vertical-actually 30 oif vertical. This orientation of the rack has been found to be quite satisfactory Where there is not much front-to-back space on a shelf of a bathroom cabinet or where unusually long lipsticks or brushes are to be stored. It also has been mentioned earlier and will be repeated here for convenience that the rack may be set with either end wall 12 lowermost in which event the elongated frame 14 extends in a vertical direction and the rank of tubular repositories likewise is arranged in a vertical direction with each individual repository being disposed in a substantially horizontal orientation. This arrangement of the rack is desirable where there is considerable head room in the space in which the rack is placed.

The top face of the rack constitutes a roof 40 which extends rearwardly from the front face 26 when said front face is Vertical and which also extends from end wall 12 to end wall 12. The roof, like the other components of the rack, is of thin, sheet-like configuration, being only thick enough to be self-supporting, stif and strong. The roof is externally broken up into a series of parallel straight ribs 42 that extend from end wall to end wall and which define a front-to-back array of parallel straight troughs 44. These troughs are of slight front-to-back (crest-to-crest) width, for example, in the order of threeeights of an inch, and are rather shallow, for example, in the order of one-eighth of an inch, being thereby dimensioned to receive elongated slender objects like bobby pins, Q-tips, pencils, nail files, etc. The front wall of each rib is at a rather steep angle to the horizontal plane of the top edges 22, eg., 60, while the rear wall of each rib is at a smaller angle to the horizontal plane, e.g., 30, so that the crest of each rib is approximately right-angled. The majority of the ribs 42 have their ends located at the inner corners of the top edges 22, so that the narrow surfaces of the top edges are uninterrupted. However, desirably, at least one rib and optionally more ribs, extend out onto the surface of the top edges so as to form protuberances 46 which project upwardly therefrom.

The bases of the troughs 44 are at the level of the top edges 22 and the upper edge of the upper segment 32 of the front face of the frame.

Furthermore, at the rear of the roof I provide a squat upwardly extending tiange 48 the ends of which extend out over and run into the narrow surfaces of the top edges 22 so as to form end protuberances 50. The crosssections of the protuberances 50 matches the shapes of ythe notches 24 so as to be snugly nestable therein.

Adjacent the bottom edge of each of the end walls the inner surfaces of said end walls are formed with shallow notches 52 (see FIGS. 2 and 6). Said notches are vertically registered (with the bottom edges 16 lowerrnost) with the protuberances 46 constituting the ends of the central rib 42. l

y.Although it will be found that a single rack provides a vconsiderable storage space for cosmetic articles and that the rack does not utilize a great deal of space inasmuch as thetubular repositories are quite close together, and inasmuch as the top edge of each mouth 34 is'near the top of the rack while the bottom edge of each bottom wall 38 is near the bottom edges 16, nevertheless, where a very large number of tubular cosmetic articles, particularly lipsticks and the like, are to be stored, it is desirable to stack the racks vertically, as indicated in FIG. 5, and it is for this purpose that the notches 24, 52 and the matching' protuberances 46, 50 have been provided. With any given rack lowermost and with its bottom edges 16 resting on a horizontal dat surface, another rack may be superimposed upon the same with its notches 24 receiving the ends 50 of the flange 48 and its notches 52 receiving the ends 46 of the central rib 42. This mating intercoupling between the protuberances and notches stabilizes the stack of racks and tends to prevent any rack from sliding in a front-to-back direction with respect to its subjacent rack. Any tendency to slide in an end-to-end direction is discouraged by abutment of the end walls of the protuberances 46 against the vertical flat bases of the notches 52, the bases of said notches in any given rack being spaced apart only a few thousandths of an inch more than the length from end-to-end of the overly long rib 42 (see FIG. 6). Thereby the bottom edges 16 rest flatly on the top edges 22.

It will be appreciated that due to the sloping upwardly presented surfaces of the protuberances 46 and the correspondingly sloped surfaces of the notches 52, such surfaces will cam upon one anotherto fully couple the protuberances and notches if, when they are vertically stacked, they happen not to be precisely vertically registered.

Attention is directed to the fact that aside from its use as a storage container for articles and particularly for cosmetic articles, the rack may be gainfully employed as a point-of-sales display or as a container in which merchandise is packed for sales. In the latter event, an appropriate transparent cover will be furnished.

It thus will be seen that l have provided a storage rack which achieves the several objects of my invention and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as Various changes might be made in the embodiment above set forth, it is to be understood that all matter herein described or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
